Specification of Letters Patent. Patented May 24:, 1921.

Application filed ill/lay 15, 1920. Serial No. 381,678.

To all whom it may concern:

Be it known that I, TOKUJI NAEMURA, subject of Japan, residing at No.138 Isobe- Dori, Sanchome, Kobe, Japan, have invented new and usefulImprovements in Matting, of which the following is a specification.

This invention relates to matting woven with filaments of grass bundledinto comparatively flat and wide cords, with thinner filaments on bothsides of each cord as the warp and weft, thereby filling up intersticeswhich would otherwise be left between warps and woofs by theirinterlacmg. An object of this invention is to obtain a strong anddurable matting having comparatlvely smooth surface and no biginterstices between warps and wefts. Another object 1s to improve theappearance by weaving thereinto any desired number of warps or wefts,

or both, of different widths, thereby forming striped pattern.

The accompanying drawing shows matting woven according to my invention1n which:

Figure 1 is a general plan v1ew.

Fig. 2 is anenlarged plan v1ew showlng the texture.

Fig. 3 is a section taken on the line 33 of Fig. 2.

Fig. 4 shows one form of cords to be used as the warp and weft.

Fig. 5 shows another form of the warp and weft.

Fig. 6 shows a form of filaments to be used for filling up intersticesbetween warps and wefts.

Fig. 7 is an enlarged plan view showing longitudinal stripes, and

Fig.8 is a section of Fig. 7 on the line 8-8.

Fig. 9 is an enlarged plan view showing transverse stripes, and

Fig. 10 is a section on the line 10-'-1O of Fi 9.

The same reference number refers to the same or corresponding partthroughout all the figures.

In Fig. 1, 1 is the ground of the matting while 2 and 3 are respectivelylongitudinal and transverse stripes. In the figure, stripes are shown asformed near the edges by way of a border pattern, but I need not saythat such stripes may be formed at any desired part.

The ground of my matting is woven, as is shown in Figs. 2 and 3 with thewarp and weft 4 of straw, rush or any other grass 5 generally used forsuch purpose, braided as shown in Fig. 4, or twisted as shown in Fig. 5,into flat and broad cords. Such cords however become very stiff bybraiding or twlsting, and when woven into a fabric, there will bebetween warps and wefts big interstices left by their interlacing. Thus,the fabric is not only unsightly, but becomes easily worn, as itssurface is uneven. Now, this drawback can be avoided by placing smallerand more flexible filaments 7 on both sides of each warp and weft. Thesefilaments 7 for filling up interstices are also straw, rushes or anyother grass collected into any desired thickness but not braided nortwisted, so that they retain their flexibility. Or if desired they maybe wound with thread 6 as shown in Fig. 6. Thus, according to myinvention three warps and three wefts are used, one braided or twistedcord 4 at the middle with two flexible ones 7, one on each side; and thefabric woven in this way is comparatively more even in its surface andcompact in its texture, and consequently pleasing to sight and durablein use.

To weave stripes into matting at any desired place, replace any desirednumber of warps 7, 4, 7 with thinner warps 8, preferably colored, of thesame kind of material with which the ground is woven, or of cotton orhemp threads collected into any desired thickness, or of cords of cottonor hemp fabric, passing this time only one warp through one heddle-eye.Then weave any desired number of warps of similar kinds as are used forforming longitudinal stripes at any desired places, passing only oneweft at each shed. In this way, longitudinal and transverse stripes canbe formed.

I claim:

1. A matting woven with warps and wefts each of which-consisting of acomparatively wide cord with cords for filling up interstices one oneach side, each set of the three cords of the warp and weft being wovenas one, and in which transverse stripes are formed by replacing some ofthe wefts consisting of three cords with a number of single wefts,substantially as and for the purposes hereinbefore set forth.

2. A matting woven with warps and wefts each of which consisting of acomparatively Wide cord with cords for filling up interstices one oneach side, the set of the three cords of the warp and Weft being wovenas one, and in which longitudinal and trans verse stripes are formed byreplacing some of thewarps' and wefts of three cords each with a numberof single warps and single wefts, substantially as and for the purposeshereinbefore set forth In testimony whereof I have signed my name tothis specification.
